Thermoplastic Rubber (TPR)與Thermoplastic Elastomers(TRE)的分別?

ThermoPlastic Rubber (TPR) is best described a material which has both the characteristics of rubber and plastic. Typical applications are the hard rubber/plastic soles on many shoes or the the rubber/plastic material used on hane tool grips.

ThermoPlastic Elastomer (TPE) are a softer version of TPR. TPEs permit fabrication of "rubber-like" articles with the speed, efficiency, and economy of injection molding, extrusion, or blow molding. This material is typically used where flexibility and soft-touch is desired in the application.
